Abstract

The method according to the invention provides that the gravimetric weighing is to be continued during the refilling of a gravimetric metering device (1) for bulk material, in addition the refilled bulk material mass is to be determined during refilling via a refilling container (3) in order to determine in real time or on average the actual mass flow which is output during refilling and to control it with regard to a desired mass flow.
